8 Claims.

This invention relates to guard structures of the character employed in covering windows to prevent unauthorized entry therethrough, and the primary aim is the provision of an entire window assembly having as a part thereof the aforesaid guard that automatically moves to the operative position as the window sash is shifted to open a portion of the window frame.

One of the important aims of this invention is the provision of a guarded window assembly, the expansible grille whereof is specially designed for shifting from an operative position when the window sash is closed, and further constructed to have unique housing parts for cooperating with the window sash and frame to enclose the expansible grille when the sash is in a shut position.

Other objects of the invention include the specific arrangement of parts forming the grille assembly and that permit shifting the grille to an inoperative position only when the window sash is closed; the provision of specially designed guide channels that have gates provided therein for releasing the grille to the inoperative position; and unique brackets for swingably supporting the grille whereby the same may be easily shifted to and from a place where it is in engagement with the movable window sash.

Other aims of the invention will appear during the course of the following specification, referring to the accompanying drawings wherein:

Fig. 1 is an elevational view of a guarded window assembly made in accordance with the present invention, and with parts broken away for clearness of disclosure. I

Fig. 2 is an elevational view of a window assembly including the frame and sash thereof, showing the guard in the operative position with one of the window sash opened.

Fig. 3 is an enlarged fragmentary horizontal condensed sectional view through the window assembly of Fig. 1, taken on line III-III of that figure.

Fig. 4 is an enlarged fragmentary detailed sectional view taken on line IV-IV of Fig. 1.

Fig. 5 is an enlarged fragmentary elevational view of a portion of the guarded window assembly showing the manner of mounting the grille.

Fig. 6 is an enlarged fragmentary sectional view taken on line VI-VI of Fig. 2; and

Fig. 7 is a similar sectional view taken on line VII-VII of Fig. 2.

The conventional window assembly with which the guard made pursuant to my invention is combined, comprises a window frame broadly designated by the numeral H], a slidable lower sash 2 I 2 and a similar sash l'4. These sashes are vertically shiftable and as is the present practice, the lower sash I2 is moved upwardly or to the position illustrated in Fig. 2 to open the window.

The guard portion of the assembly comprises the collapsible grille which automatically expands to an operative position when sash I2 is lifted. When the sash is lowered to shut out the elements, the guard assumes the position illustrated in Fig. 1.

Sash l2 has a pair of lifts [6 with each of which is associated a bracket l8 having a notch or slot 20 therein to receive head 22, rigid with the uppermost portion of the grille assembly.

The grille per se comprises a number of horizontally disposed bars 24 interconnected by angular links 26, pivotally fastened to bars 24 by rivets or the like 28. Bars 24 confine links 26 therebetween, as illustrated in Figs. 4, 6 and '7, and when the grille is collapsed, links 26 are in superimposed parallel relation between bars 24 to present a compact body swingably about pintle 35 in a manner hereinafter more fully set forth.

Each bar 24 has a longitudinally extending guide lug 32 at each end thereof, and these guide lugs ride in channels 34 attached to frame ID, as clearly shown in Figs. 3 and 5.

Channels 34 are double in character, that is, there is an inner channel mounted within an outer channel for longitudinal sliding movement, and it is this inner channel which is shifted upwardly when the collapsed grille is to be swung outwardly around pintle 30. The outer channel is cut away as at 36 to present a notch or opening great enough to permit the collapsed grille to drop inwardly away from sash 12 when the said sash is closed. Notch 20 permits the escape of head 22 when this action is desirable. Pintles 30 are journalled for rotation in openings 38, formed through the base or bights of channels 34. The inner channel extends slightly above the outer channel when notch 36 is closed and a laterally disposed lug 40 on one leg of the inner channel afiords an easy grip for the operator to lift the inner channel longitudinally of the outer channel to free guide lugs 32, as seen in Fig. 5. Under such conditions, the entire grille assembly may be moved outwardly and downwardly gainst sill 42 of the window structure.

Anapron 44 formed as shown in Fig. 4, confines the collapsed grille therebehind when sash I2 is closed-thus, a housing for the grille is created and one of the movable parts thereof is exposed to view when the window is in the shut condition.

Apron 44 is but slightly higher than the top rail of the lower sash l2, and therefore, when the window and grille are closed as viewed in Fig. 4, very little obstruction is presented to the window pane or glass within this sash 12.

When the window sash is raised and the grille is opened to a greater or lesser degree, depending upon the position of sash I2, apron 44 will not obstruct the passage of air through the opening for the lower edge of apron 44 is slightly above the lower edge of the lower rail of sash l2. The position of the lower edge of this apron 44 is such as to preclude its striking sill 42 as the collapsed grille is swung around the axis of pintles 30.

From the foregoing, it is obvious that the guard for the conventional window assemblymay be affixed to any type of window having vertically movable sashes, and when the parts are in the assembled position with channels 34 in a closed position, the grille serves as a definite guard against the unauthorized passage of a .body through the .open window when sash i2 is lifted. No manipulation from outside the window will dislodge the parts of the guard and only when the win-- dow cash 12 is closed can the grille be swung to an inoperative position. Such swinging cannot occur accidentally for it is necessary to raise the inner channels which are solid throughout their length to (points above the .cut away portions of the outer legs of the outer channels .in which are formed notches 35.. Thus, the inner channels become gates to lope-nand-close notches 36 of the outer channels and through this arrangement of parts, the grille is assembled and made inoperative or operative as the user chooses.

Manifestly, the use :of guarded window assem- :blies such as those illustrated and described present neat and effective means for covering open windows without presenting barriers to the passage of air. The grille is as effective as bars solidly secured to the window frame, yet the unsightly appearance of bars is avoided. Details of construction may be varied without departing from the spirit of the invention or scope of the appended claims.

Havin thus described the invention, what is claimed as new and desired :to be secured by Letters Patent is:
